VALVE.

Specification of Letters Patent.

Patented April 24, 1906.

Application filed September 22. 1904. Serial No. 225,521.

To all whom it may concern:

Be it known that I, MIGHAEL J. OoNNoRs, a i

citizen of the United States, residing at Kansas City, in the county ofJackson and State 5 of Missouri, have invented certain new and usefulImprovements in Valves; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to valves for steam, water, or air mechanism.

It has for its object to provide a novel form of valve which is simplein construction, cheap of manufacture, and which may be normally held ina closed position.

The invention consists, broadly, of a longitudinally-movable tubemounted within airtight packing-rings in an outer casing which isprovided with a water-tight chamber at one end, into which the end ofsaid tube may be pushed to shut oil the flow. When the tube iswithdrawn, the liquid passes through a bypass around said water-tightchamber. 5 The invention also consists in certain means forautomatically operating the tube to shut off the valve and in the otherdetails of construction and combinations of parts hereinafter described,and more particularly pointed out in the claims.

In the accompanying drawings, illustrating the preferredembodiment ofthe inven tion, Figure 1 is a longitudinal view of the valve with itsparts assembled and a coiled 5 spring placed behind the tube, holding itnor mally closed. Fig. 2 is a crosssectional view taken on the line 00 wof Fig. 1. Fig. 3 is a top lan view of the valve with the handle or knobbroken away. Fig. 4 is a sectional view of a valve provided with adifferent means of operating the same, consisting of a lever and link, aportion of the casing being broken away to disclose the construction ofthe slidable tube. Fig. 5 is a broken sectional view showing thearrangement of the inclined lever for actuating the valve. Fig. 6 is abroken view showing a bent spring arranged to automatically operate thevalve, and Fig. 7 is a longitudinal sectional view of a modified form ofvalve having a screw-ring to operate it. Fig. 8 is a detailed view ofspring 24.

Although the preferred embodiment of my invention is fully shown in theaccompanying drawings and the construction and operation are describedin the following specification, the right is reserved to make suchchange from the constructions shown and described as the scope of theclaims hereto appended will permit.

In carrying out my invention I provide a casing comprising a centralportion 1, .end portions 2 and 3, and an intermediate ring 4, arrangedbetween the central portion and the end portion 3. The casing as a wholeis gen erally cylindric in form. The central portion has a slot 5 in itsupper surface and two upstanding arms 6, one on each side of said slot.A hand-lever 7, having an enlarged head 8, is pivoted between said arms6 and has a series of gear-teeth 9 on its lower end. Said teeth engagelugs or teeth 10 on the cylinder or tube 11, which is mounted to movewithin the casing. One end of the central portion of the casing isexternally screw-threaded to receive the end piece 2. A circular recess12 is provided in this end of the central portion for packing-rings 13,which may be of leather-or other suitable material. The bore of thegreater portion of said end piece is the same as that of said centralcasting to permit the tube or cylinder to extend thereinto; but a step14 is formed where the bore is restricted to confine said tube. Theother end of the central casting is internally screw-threaded to receiveone end of the connecting-ring 4, the other end of said connecting-ringbeing internally-screw-threaded to receive the externally screw-threadedend piece 3. A recess is provided between the connecting-ring and thecentral piece for packing-rings 15.

FiXedly arranged within the end piece 3 and held in place by integraltie-arms 16 is a chamber 17, opening toward the slidable tube. Saidchamber is packed, as at 18, at its opening, so that it fits around theend of said tube when the latter is pushed into engagement therewith,making a water-tight joint and effectively cutting off the flow.

When the tube is withdrawn, the liquid passes around the chamber 17 bythe by-pass 19. The chamber 17 should be airtight, so that when the endof the tube is thrust into engagement therewith all flow through saidtube will be entirely out off. The weight of the handle shown in Fig. 1of the drawings may be sui'liciently great to normally hold said tube inengagement with said chamber by virtue of said handle always lyingoflcenter, or the lever or handle may be inclined rearward, as in Fig. 5.In this construction a groove 20 is formed in one of the arms, betweenwhich the handle-lever is pivoted, into which groove is inserted a flatspring 21, adapted to bear against a pin 22 on said handle, therebypressing the latter rearward when released and shutting off the valve.

Other means of operating the valveare shown in Figs. 4, 6, and 7. In thefirst of these figures the lever is pivoted at one end portion of thecasing and the tube has a shank or arm 22 projecting through the slot inthe casing, said arm 22" and the handle being connected pivotallytogether by a link 23. In Fig. 6 a bent spring 24 isinserted into theslot in the casing of the construction shown in Fig. 1, said springlying between the two teeth or lugs on the tube with each of the ends ofsaid spring extending into a groove 25in opposite sides of the casing.The tendency of said spring is to normally shut off the valve. In theconstruction shown in Fig. 7 a loose internally-threaded nut 26 ismounted around the central portion of the casing and confined betweenthe enlarged ends 27 thereof. A shank or pin 28, fixed to the tube,extends through the slot in the casing and into the groove between thethreads of the nut, whereby when the nut is turned the tube is movedendwise to operate the valve. ably square to render its movement easy.Still other devices for operating the valve may be used withoutdeparting from the spirit or sacrificing the advantages of my invention.

My construction whereby I provide a water-tight chamber into which thetube is adapted to be thrust is a great advantage over merely bringingthe end of the tube in contact with a solid seat in that when the end ofthe tube is pressed into said chamber within the packing-ring it willhold its position of its own accord and will constitute a positivecut-ofi'. Were the end of the tube brought into engagement with a solidseat, it would be necessary to apply'a continuous external pressure tokeep it in such contact and prevent leakage.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
